Application at men 2 This invention relates to a loop for use in fastening and holding various articles but particularly articles of clothing such as sanitary napkins.

The principal object of the invention is to provide for this purpose a loop of very simple character in which the clamping bar will be held in clamping position by friction so'that it cannot be removed therefrom except by the exertion ofa direct force against it and cannot be removed by pulling on the garment which is attached to it.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to theaccompanying drawings in which:

Fig. 1 is an elevation showing a preferred form of the loop as employed for attaching a sanitary napkin to another garment; Fig. 2 is a sectional view of the same onthe line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1 showing the loop substantially in clamping position without the articles to be fastened;

Fig. 4 is a sectional view of the same on the line 4.4 of Fig. 3; s

Fig. 5 is a View of the piece of wire which constitutes the frame of the loop;

Fig. 6 is a view similar'to ig. 3 of a modification but showing the clampingbar in raised or inoperative position; an

Fig. 7 is an edge view of the same.

Loops having the same general appearance and used for similar purposes are now on the market, but in these loops the "clamping bar is loosely mounted on the frame so that it is free shown in Fig. 3 to that and does not offer any resistance against such motion, whereby they are likely to become loose and fail to perform their function. 7

Referring to the form shown in Figs. 1' to 5, the frame consists of a single piece of wire 10 having two ends 11 which diverge from each other in the condition shown in this figure. The sides of the loop are formed of a horizontal bottom wire and the two ends 12, and these sides are parallel. To complete the frame itself a tube 13 is provided, receiving the two ends 12 and permitting them to move along it a the ends 11 of the frame are moved back and forth. This provides a certain amount of flexibility and the set of the wire frame to move from the position shown in Fig. 6

normally holds these. ends in the position. shown-in Fig. 5 if no force is applied.

The clamping bar 14 consists of 'a fiat piece of sheet metal, preferably with a center pro ection at the bottom which is adapted to engage over the bottom straight bar of the frame to clamp a piece of cloth thereto. As stated above, this clamping action is relied upon in the devices now on the market and there is no resistance except the friction of the bar 14 on the bottom horizontal bar of the frame 10 to hold the parts in clamping position. 1 Withmy invention, however, the passages which are formed throughthe ends of the clamping bar 14 as shown in Fig. i are just large enough so thatwhen the clamping bar is down in clamping position asshown in Fig. 1 the ends 11 of the frame bear against the outer sides of these passages 15 at the top with a certain amount of friction. force is applied directly to move the clamping bar upwardly, this friction is enough to hold it and if force is applied the friction grows stronger if the clamping bar is moved slightly as it has to overcome the resiliency of the wire frame and the natural divergence of the ends 11.

This clamping bar, as indicated in Fig. 6, will tion on account of that friction until it is moved therefrom instead of droppin down, interfering with the threading of the garmenfi through the loop.

The principal object of my invention, however, lies in the fact that when a piece of tape, gauze or other cloth 16 is passed over when moved to the top stay in that posi- If no the clamping bar and down behind the frame it will stay there, as the clamping bar is frictionally held in position at its ends. Any pulling on the tape 16 will not dislodge it or lessen the clamping efi'ect. This loop of course, is intended to be connected to another garment 17 by doubling it over the top of the frame and sewing it as is wellunderstood in this art.

The frame shown in Figs. 6 and exactly the same way, except of the wire frame are flattened at 18 so as to provide projections 19 at bearing even more efliciently on the passages 15 of the clamping bar 14 to hold it in 7 works in I lthough I have illustrated and described only two forms of the invention, I am aware their outer surfaces that the ends of the fact that other modifications can be tance between said ends at the wider side, made therein by any person skilled in the and a sliding clamping bar parallel with art Without'departing from the scope oi the said sides and having passages at its 'ends invention as expressed in the claim.
